please help

HI, I love the addon, it does everything I need, apart from one thing. some of my chairs do not have colours…. and I only want to display colours, not other options. Because I have so many different colour attributes for different products, I cannot just select colour attribute as some colour options are fabric colour, wood colour, desk colour etc. so I have set it to display the first attribute, which is fine unless there are no colours. How can I hide this from displaying on the archive/shop page on an individual product basis? Or is there a workaround? I would rather nothing show rather than show arm options etc. I just want colours to show. Many thanks hope that makes sense
